4 Claims.

My invention relates to dish washing devices and has for its primary object the forcing of water under pressure against the dishes to be cleaned.

A further purpose is to utilize the usual household sink as the receptacle wherein the dishes are placed for cleaning.

A further purpose is to hang a motor and pump unit from the usual faucets of a household. sink.

A further purpose is to provide suspension means for a motor and pump which will permit the motor to be swung in an arc of 90 degrees and held in either of two positions.

A further purpose is to construct a device which may be used as an attachment upon the existing faucets of the usual household sink without special tools or skill, and which may be attached or removed at will.

A further purpose is to provide a hose through which water may be lifted from a sink by the action of a pump, and by the action of the same pump to force the same water against the dishes to be washed.

A further purpose is to have a spray nozzle at the end of a hose connect with the outlet from the A further purpose is to detachably mount a pump and a motor support upon faucets above a sink bowl, with one end of the support acting as a pivot about one faucet and the other end adaptable for spring latching engagement with another faucet, so that the pump may be moved to a lower position for priming.

A further purpose is to position a motor driven pump above a sink bowl, to provide an inlet for the pump adapted to connect with water in the sink, to provide an outlet for the pump and to mount the pump on a bracket so that the pump is swingable into and out of position above the sink bowl.

I have elected to show one only of the various forms in which my invention could be presented, selecting a form which is practical, effective and convenient, the selection of which has been governed primarily by the convenient illustration of the principles involved.

In the drawing:

Figure 1 is a top plan view of a sink, showing the two faucets in connection with a single outlet and having my invention attached thereto.

Figure 2 is a front elevation of the structure shown in Figure 1.

Figure 3 is a horizontal section taken on the line 3-3 of Figure 2.

I have illustrated a kitchen sink of usual design indicated at H, having the accustomed hot and cold water supply faucets I2 and I3, and sunken basin M. A group of soiled dishes P5 in a suitable container, such for example as an open mesh wire basket l5, are placed within the basin I! of the kitchen sink H.

In the figures, I have shown a combination fixture, i. e. two faucets having a single outlet. A suitable bracket 16 designed to snap over portions of the two faucets, supports a motor I! and a pump l8 directly connected with the motor. Wires for current supply for the motor are indicated at l9.

The pump has an inlet port 20, and an outlet 2!. Attached to the inlet 20 is a flexible hose connection 22. Attached to the pump outlet 2| is a second flexible hose connection 23, which carries a spray nozzle 24 at its outer free end.

In operation the basin I4 is filled by opening the faucet l2 and allowing hot water to fill the basin to a suitable level. The soiled dishes are placed within the open mesh wire brasket, and the basket is then set in the basin l4 submerging the dishes. Suitable soap or soap powder is added to the water, the bracket l6 carrying motor H and pump I8 is attached to the faucets and the hose 22 is dropped into the water within the basin. The wires conducting the current are now attached to the electric outlet and the motor is started.

If priming of the pump be necessary, the inlet hose 22 is placed in contact with the faucet outlet and water from the faucet is run through the pump, and then the inlet hose is returned to the sink. The pump l8 draws water from the sink to the pump and forces it out therefrom under the pressure through the hose 23 and the spray nozzle 24. The spray nozzle 24 is manipulated over and about the soiled dishes, forcing the soilage from their surfaces. This operation is continued until the dishes are thoroughly cleansed at which time the seal of a suitable stopper is broken and the used soapy water is allowed to drain from the sink basin M.

It will be evident that I may and ordinarily will pump soapy water from the sink and spray it back into the sink.

In order to rinse the cleaned dishes, the inlet is forced over the discharge end of the faucet. Hot water is then again turned on and the motor started, drawing the water diirectly from the faucet to the pump and forcing it from the pump out through the hose 23 and spray nozzle 24. The hose will then again be manipulated over and about the dishes.

When the dishes have been sufficiently rinsed the water supply and the electric supply are both shut off and the basket containing the dishes is removed to the drain board where the dishes may be permitted to drain, or can be wiped dry in the usual and well known manner.

A motor I! connected with a pump I8 is pivoted in a bracket 25, suspended from the supporting bracket 16. The bracket l6 carries a suitable detent plunger 26 which is adapted to cooperate with detent notches 21 and to hold the motor in either one of the two positions shown in the drawing. The pump inlet may be placed nearer the source of water supply during the operation of the pump in order to shorten the lift, and the motor and the pump may be swung out of the path of the basket containing the dishes during its placement in and removal from the basin of the sink.

For convenience in priming the pump, where this is necessary, I illustrate in Figures 1 and 2 a detachable support for the pump unit comprising a spring finger I6 on the support Hi. The other end of the support l6 may be constructed as shown in Figures 1 and 2 with a spring clip which almost encircles the circular portion of the faucet, so that the pump may readily be brought close to or below the water level in the sink by swinging about the left hand faucet of Figure 2.

My invention is particularly convenient for installation on existing sinks, but it will be evident that the essential parts may be combined with or built into a sink structure if a special sink is to be designed. Changes of this sort, however, will not alter the essential operation of my pump.

It will be obvious that the ends of the inlet and outlet tubes are adapted to use respectively as suction and pressure scrubber members. A user of the device may scrub a dish surface carrying adhering matter with either tube end or first with one end and then with the other according as pressure or suction scrubbing is most advantageous or alternate suction and pressure scrubbings are most advantageous. As

is well known, the combination of scraping with a tube end and of rapidly inwardly or outwardly flowing water at the tube surface is very effecthe for cleaning the surface. The suction scrubber is quieter and avoids splashing in use while the pressure scrubber does not draw the removed material through the pump.

In view of my invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the structure shown, and I, therefore, claim all such in so far as they fall within the reasonable spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a dish washing device, in combination with a sink bowl adapted to hold water, a motor-driven pump above the sink bowl, an inlet hose for the pump adapted to connect with water in the sink, an outlet hose for the pump and a bracket supported above the bowl mounting the pump on the sink swingable into and out of operative position in the sink.

2. In a dish washing unit for a sink having two faucets, a motor-driven pump, a supporting frame for the pump adapted to be attached to the faucets and a supporting bracket rigid with the frame and pivotally carrying the pump.

3. In a dish washing unit for a sink having two faucets, a motor-driven pump, a supporting frame for the pump adapted to be attached to the faucets, a supporting bracket rigid with the frame and pivotally carrying the pump and means for holding the pump in a plurality of angular positions.

4. In a dish washing unit for a sink having two faucets, a combined motor and pump and a support for the pump, said support to hold the pump from the faucets, and having pivot connection with one faucet and a spring latch interlocking with a side of the other faucet adapting it to swing down for priming the pump.
